Stock '06 5M's are geared for 190mph
 

Forgive me but I'm really bored right now.

Disclaimer: I chad68 have no desire to make my Z go 190MPH. Kids don't try this at home.

In theory 190 mph would be the top speed if you "could" hit redline in 6th. (according the factory speedo anyway)

Don't believe me? Drive at 3,500 RPM in first gear check your MPH, then go to redline and look again at the speedo. Now do that for 2nd, 3rd, 4th and 5th gears (if you dare). I have done 3,500 and 7,000 RPM in the first 5 gears and it is exactly accurate.

So how much more HP would the Z need to be able to hit the 7,000 RPM redline in 6th gear?

uhhh maybe if you drove in a frictionless environment with no wind factor....just maybe....

sorry man, i dont exactly get what you'r saying...the factory speedomiter goes up to 160. i wish it went to 190.

-d(a(du/dx))/dx+(d^2(b*(du^2/dx^2)/dx^2))+co*u+c1*(du/dt)+c2*(du^2/dt^2)=f(x,t)

When b=0, c2=0, co=0, c1=rho*A, a=kA

e=mc2 :icon14:

if that's true, i'd love to think what the hr could do.

try it on some salt flats

I thought that was the formual for the flux capactior.

Wow... This post makes my car hurt.

ya 155 is to slow........... thats almost redline in 5th wich ihave done countless times in my 06 gt roadster! i wish we could use 6th.........

what are you on? this is not a Murcielago your driving now.:confused:

Nice theory. Here it is in the real world....

But...you can't.

Most cars, including teh Z are "torque" or "drag" limited.

As speed increases, the wind resistance (drag) will exceed the amount of torque available to overcome it.

Only 190 in 6th? The 07's can hit 218 or so.

Well... maybe... with a 200mph tailwind.

I know stock it could never hit 190 at least on Earth but I know there is some kind of formula you could use to roughly figure out how much HP it would take.

Thanks for the link, that was cool. Guess I need 14 PSI of boost!!!

Kidding.

The rsx can do 190 in 2nd gear. N02 stickers and neon lights make it even faster! :-\
